I saw dozens of threads mentioning that the e46 was the last of the DIY friendly BMW (that also means everything released after the e65) and now I see you doing DIYs on an e92 M3 Is it really easy or you're so much mechanically/electrically inclined?? And btw got 240k on my e39 540 here..I recently bought it and everything is solid..no problems at all

I've been working on cars for a long time as a hobby, so I can do some of the more complicated stuff, but everything I've done so far is pretty easy. The spark plugs were easy too, but a couple of them take a little patience.

I had a 2002 530i E39 and it was probably the best car I've ever owned. I had 230K miles on it when I gave it to one of my daughters, and it gave her great service until it got hit by a drunk driver and totaled. Have you owned the 540 since it was new?
